Abstract
The invention discloses a part surface spraying treatment process. The part surface spraying treatment process is characterized by comprising the following steps of plastic product heating, ionization air dedusting, primer paint air spraying, leveling, finishing paint air spraying, 10-min leveling and drying; a plastic product is heated to 40-60 DEG C; primer paint air spraying is electrostatic spraying, two-component polyurethane primer paint is adopted for spraying for 2-3 times, and leveling time is 5-10 minutes; finishing paint air spraying is electrostatic spraying, and a wet-on-wet method is adopted for spraying two-component polyurethane finishing paint; and the drying temperature is 70-75 DEG C, and drying time is 30-60 minutes. According to the part surface spraying treatment process, spraying process defects can be reduced, the spraying surface quality is improved, and the product quality is improved.
Description
Technical field
The invention belongs to spraying coating process field, specifically a kind of piece surface spray treatment technique.
Background technology
Plastics (acrylonitrile, butadiene and styrene copolymer) belong to type thermoplastic resin plastics, have higher mechanical strength and good processing characteristics, but its hardness is low, and weather-proof, poor solvent resistance can be improved by the secondary operations of frosting.Spraying is one of important method of frosting secondary operations.There are the problems such as adhesion effect bad, loss of gloss, pit often in spraying in plastics plastics, its reason mainly has, surface tension (less than 100mN/cm), resin in solubility parameter and coating, solvent solubility parameter differ greatly, the internal stress produced when molding is easily generated paint film crackle or reduces the defects such as coating gloss, surface is easily generated electrostatic and absorption dust, affects spraying effect.
Summary of the invention
In view of the deficiency that prior art exists, it is an object of the invention to provide a kind of piece surface spray treatment technique, spraying coating process defect can be reduced, improve sprayed surface quality, improve product quality.
The technical scheme realizing the object of the invention is as follows:
A kind of piece surface spray treatment technique, it is characterised in that its spraying coating process comprises the following steps:
Plastic heats → ionized air dedusting → aerial spraying priming paint → levelling → aerial spraying finish paint → levelling 10min → drying；Described plastic heats to 40-60 DEG C；Described aerial spraying priming paint is electrostatic spraying, adopts Two-component polyurethane primer to spray 2～3 times, described flow time 5-10min；Described aerial spraying finish paint is electrostatic spraying, and adopting wets touches wet spray two component polyurethane finish paint；Described drying temperature is 70～75 DEG C, time 30-60min.
A kind of piece surface spray treatment technique of the present invention, can reduce spraying coating process defect, improves sprayed surface quality, improves product quality.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and its operating procedure is as follows:
A kind of piece surface spray treatment technique, its spraying coating process comprises the following steps:
Plastic heats → ionized air dedusting → aerial spraying priming paint → levelling → aerial spraying finish paint → levelling 10min → drying；Described plastic heats to 40-60 DEG C；Described aerial spraying priming paint is electrostatic spraying, adopts Two-component polyurethane primer to spray 2～3 times, described flow time 5-10min；Described aerial spraying finish paint is electrostatic spraying, and adopting wets touches wet spray two component polyurethane finish paint；Described drying temperature is 70～75 DEG C, time 30-60min.
A kind of piece surface spray treatment technique of the present invention, can reduce spraying coating process defect, improves sprayed surface quality, improves product quality.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should at the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by logic minute analysis, reasoning or the available technical scheme of limited experiment.
